ELM 3-240 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-240 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.240" (6.10mm) length and accommodates standard T1 3/4 LED packages. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct component replacement in circuit board designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-240 are qualified based on the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• RoHS Compliance: ROHS3 Compliant (all substitutes meet this requirement)
• MSL Rating: 1 (Unlimited) (all substitutes maintain this rating)
• Packaging: Bag (all substitutes use identical packaging)

Secondary Substitution Parameters:

• Length tolerance: 0.235" to 0.250" (6.10mm ±0.15mm range)
• Material: PVC or Nylon construction
• Series designation: ELM 3, ELM 1, or 909 series

Substitutes are grouped into two categories: same-length equivalents (ELM 1-6MM, ELM 3-240 variants) and length-variant equivalents (ELM 3-235, ELM 3-250, ELM 1-250, 909-235 BK). All substitutes maintain T1 3/4 LED accommodation and black color specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): ELM 1-6MM provides identical electrical and mechanical parameters to the ELM 3-240, with matching 0.240" (6.10mm) length and PVC material composition. Both parts maintain Active product status and ROHS3 compliance. Selection between these parts depends on series compatibility requirements within the design.

Length-Variant Substitutes (Same LED Type, Adjusted Height): ELM 3-235 and ELM 3-250 offer length variations within the ELM 3 series, accommodating 0.235" and 0.250" specifications respectively. These parts maintain PVC material and ROHS3 compliance. ELM 1-250 provides equivalent functionality within the ELM 1 series at 0.250" length.

Material-Variant Substitute (Nylon Construction): 909-235 BK substitutes nylon material for PVC at 0.235" length. This part maintains T1 3/4 LED accommodation, black color, and ROHS3 compliance. Material selection between PVC and nylon depends on mechanical stress and environmental exposure requirements.

All substitute parts carry Active product status and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-6MM replace ELM 3-240 directly? A: Yes. ELM 1-6MM matches the critical parameters of ELM 3-240: identical 0.240" (6.10mm) length, T1 3/4 LED type, black color, PVC material, and ROHS3 compliance. Series designation differs (ELM 1 versus ELM 3), but electrical and mechanical compatibility is maintained.

Q: What is the difference between PVC and Nylon material options? A: The ELM 3-240 uses PVC material. The 909-235 BK substitute uses nylon. Both materials are black and support T1 3/4 LED packages. Material selection depends on mechanical durability and environmental exposure requirements specific to the application.

Q: Are length variations acceptable substitutes? A: Length variations (0.235", 0.240", 0.250") are acceptable when circuit board layout and LED standoff height requirements permit. All length variants maintain T1 3/4 LED accommodation and ROHS3 compliance. Verify mechanical clearance in the target application before substitution.

Q: Do all substitutes maintain RoHS3 compliance? A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original ELM 3-240 specification. MSL 1 (Unlimited) rating is maintained across all substitutes.

Q: What inventory considerations apply to substitute selection? A: Inventory levels vary significantly among substitutes. ELM 1-250 maintains the highest inventory (52009 Pcs), while ELM 1-6MM has lower availability (8834 Pcs). Verify current stock status for production scheduling requirements.

Q: Can substitutes be mixed within a single design? A: Substitutes should be evaluated for consistency within a single circuit board design. While all parts accommodate T1 3/4 LEDs and maintain ROHS3 compliance, length variations and material differences may affect mechanical alignment and thermal characteristics. Confirm compatibility with mechanical design specifications.
